Jowls
& Jawline Laxity
Loss of jaw definition driven by volume loss, SMAS laxity, and skin descent
Jowls form when the structural support of the lower face gives way — fat descends, the SMAS layer loosens, and skin that once sat taut along the jaw begins to droop below it. Modern non-surgical treatments can address each of these layers without surgery.
Why Jowls Form
Jowling is one of the most visible signs of facial aging — and one of the most structurally complex. It is not caused by a single factor but by a cascade of changes across multiple tissue layers happening simultaneously.
SMAS Laxity
The SMAS (superficial musculoaponeurotic system) is the structural scaffold of the lower face. As it loosens with age, everything above it — fat, skin — loses its support and descends toward the jawline.
Fat Pad Descent
The midface fat pads that give the cheeks their fullness shrink and migrate downward over time. This creates hollowing above the jaw and adds volume to the jowl area below.
Bone Resorption
The jaw and cheekbones gradually lose density and projection. As the bony framework diminishes, the soft tissue above it loses its anchor and sags forward and downward.
Treatments
Skin & Collagen Loss
Declining collagen and elastin mean the skin can no longer hold tension across the jaw. Combined with gravity, the lower cheek and jowl skin progressively loses its upward resistance.
Treatment Spotlight
EMFACE: Lifting From the Muscle Up
Most jowl treatments work on the skin or the SMAS. EMFACE works on the muscles beneath — specifically the zygomaticus major and other lifting muscles of the midface that provide upward resistance to the overlying tissue. As these muscles weaken with age, the lower face loses its internal support and descends. EMFACE is the only non-invasive treatment that directly re-tones these muscles, restoring the foundation of lift from within rather than tightening what has already descended.

Ultherapy: The Only Treatment That Reaches the SMAS
Jowling originates in the SMAS — the deep structural layer that acts as the facial scaffold. As this layer loosens, everything above it descends. Ultherapy is the only non-invasive treatment that delivers energy precisely to this depth, targeting the same structural layer a surgeon lifts in a facelift. No other treatment on this page reaches the SMAS directly. For patients where SMAS laxity is the primary driver of jowling, Ultherapy is the most structurally targeted option available without surgery.

Jowl Treatments Compared
Micro-focused ultrasound (HIFU)
SMAS layer
Targets the SMAS — the same deep structural layer lifted in a facelift — with micro-focused ultrasound. Stimulates collagen to lift and tighten the lower face over 2-6 months. Single session, no downtime.
Monopolar radiofrequency
Dermis to subcutaneous tissue
Delivers radiofrequency to the full depth of the dermis along the jawline, contracting collagen immediately and stimulating new collagen for up to six months. Single session.
Synchronized RF + HIFES
Dermis + facial muscles
Re-tones the lifting muscles of the midface with HIFES electrical stimulation, restoring the muscular foundation that keeps the lower face elevated and defined.
Dual-wavelength laser
Dermis + subcutaneous tissue
Dual-wavelength laser that heats the subcutaneous layer to remodel collagen and tightens the skin surface — addressing both structural laxity and skin quality along the jawline.
3DEEP radiofrequency
Dermis to subcutaneous tissue
Sustained RF heating triggers progressive collagen tightening along the jaw and lower cheek over a course of sessions. Gradual, natural-looking improvement with no downtime.
Thread Lift
Absorbable suture threads
Subcutaneous tissue
Absorbable barbed sutures mechanically reposition jowl tissue upward for immediate jaw definition, with continued collagen stimulation as threads dissolve over 12-18 months.
Injectable Options
Neuromodulator / filler
Muscle / subdermal

Facelift Surgery
Surgical SMAS lift
All tissue layers
Surgical lift of the SMAS with excess skin removal. Most comprehensive option for significant jowling but requires general anaesthesia and 2-4 weeks recovery. Not performed at 99 Medispa — referral available.
